Description

本発明は、香箱に含まれるばねによりエネルギーが供給される機械式腕時計のムーブメントに関する。より詳細には、仕上げ歯車列を駆動するための主香箱と、最小の所定期間中機能すべき補足機能に割り当てられた歯車列を駆動するための少なくとも第２香箱とが設けられた、機械的計時器ムーブメントの稼動余力表示機構に関する。   The present invention relates to a movement of a mechanical wristwatch in which energy is supplied by a spring contained in a barrel. More specifically, a mechanical barrel provided for driving the finishing gear train and at least a second barrel for driving the gear train assigned to the supplementary function to be functioned for a minimum predetermined period of time are provided. The present invention relates to a working capacity display mechanism of a timer movement.

こうした機構は、計測時間の時間及び分を円盤を用いて表示する、クロノグラフ機械式腕時計のムーブメントに特に良好に適応する。この場合、最小の所定期間は、計測可能な最大時間に等しい。   Such a mechanism is particularly well adapted to the movement of a chronograph mechanical wristwatch that displays the hours and minutes of measurement time using a disk. In this case, the minimum predetermined period is equal to the maximum time that can be measured.

このタイプの表示器は、針による表示器よりも優れており、大きな寸法の表示の提供を可能にし、従って、例えば航空機のパイロットが望むと思われるような、より迅速により容易な読取を可能にすることが知られている。   This type of indicator is superior to the needle indicator and allows for the provision of large dimension indications, thus enabling faster and easier reading, for example as an aircraft pilot may desire. It is known to do.

そこで生じるのが、円盤を駆動するのに必要な機械的エネルギーの問題である。具体的には、単一の香箱は応力にさらされる危険があり、応力はバランスの振動の振幅を混乱させ、その結果、クロノグラフ歯車列の正確な作動を阻害する。   What arises is the problem of mechanical energy required to drive the disk. In particular, a single barrel is at risk of stress, which disrupts the amplitude of the balance vibration and, as a result, impedes the correct operation of the chronograph gear train.

ＥＰ０３ ４０５５３２．７号明細書は、計測時間の時間単位、１０分単位、及び分単位の円盤が、それぞれ独自の香箱によって駆動されるムーブメントを提案することで、この問題に対する解決策を提供している。   EP03 405532.7 provides a solution to this problem by proposing a movement in which hourly, 10 minute, and minute disks of measurement time are each driven by its own barrel. Yes.

こうした製品では、最小期間にわたってストップウォッチ機能を作動させるために、基本機能とストップウォッチ機能の両方について、ムーブメントの稼動余力の表示を有することが、装着者にとって非常に有用である。   In such products, it is very useful for the wearer to have an indication of the remaining working capacity of the movement for both the basic function and the stopwatch function in order to activate the stopwatch function for a minimum period.

本発明の目的はこの必要性に対応するものである。   The object of the present invention addresses this need.

この目的を達成するために、前述のタイプの本発明による稼動余力表示機構は、
−針と、針の位置を読み取るために使用される文字盤とを含む稼動余力表示手段と、
−それぞれ主香箱及び第２香箱を前記表示手段に連結している第１及び第２歯車列と、を含み、
−これらの手段及びこれらの歯車列は、表示された稼動余力が、補足機能が作動する残り時間に相当するように配置されている。 In order to achieve this object, the operating capacity display mechanism according to the present invention of the type described above is
A working capacity display means including a hand and a dial used to read the position of the hand;
-First and second gear trains respectively connecting a main barrel and a second barrel to the display means;
These means and these gear trains are arranged in such a way that the displayed operating reserve corresponds to the remaining time during which the supplementary function is activated.

有利なことに、表示される稼動余力は、最短の余力を有する香箱の稼動余力である。   Advantageously, the displayed operating capacity is the operating capacity of the barrel having the shortest capacity.

好ましい実施形態によると、表示手段及び歯車列は、
−計時器がストップウォッチ機能を伴わずに作動する限り、針は、主香箱の稼動時間と第２香箱の稼動時間との差に相当する稼動時間の後にのみ、移動を開始し、
−ストップウォッチ機能が作動されると直ちに、針は移動を開始して、最短の余力を有する香箱の稼動余力を表示するようになっている。 According to a preferred embodiment, the display means and the gear train are:
-As long as the timer operates without a stopwatch function, the needle starts to move only after an operating time corresponding to the difference between the operating time of the main barrel and the second barrel,
As soon as the stopwatch function is activated, the hands start to move and display the working capacity of the barrel with the shortest available capacity.

さらに、表示手段及び歯車列は、
−計時器の巻き上げが、第２香箱の稼動時間に等しい稼動時間に相当する状態に到達しない限り、文字盤は回転するが針は静止したままであり、
−巻き上げが前記状態に到達すると直ちに、文字盤と針とは同時に回転するようになっている。 Furthermore, the display means and the gear train are
The dial rotates but the hands remain stationary unless the timepiece reaches a state corresponding to an operating time equal to the operating time of the second barrel
-As soon as the winding reaches said state, the dial and the hands are rotated simultaneously.

本発明による機構の操作を、以下の４つの状況について述べる。
−最初の１０時間の巻き上げ、
−１０時間を超える巻き上げ、
−ストップウォッチ機能を伴わない稼動、
−ストップウォッチ機能を伴う稼動。 The operation of the mechanism according to the invention will be described in the following four situations.
-First 10 hours roll-up,
Roll-up over -10 hours,
-Operation without stopwatch function,
-Operation with stopwatch function.

１． 最初の１０時間の巻き上げ
爪車２５が、竜頭２０から巻き上げ歯車及び丸穴車によって駆動されると、軸２４は、主香箱２３のばねと、同時に、第２香箱３１のばねとを、可動部２７、２８、２９及び軸３０を用いて巻き戻す。 1. When the first 10-hour hoist wheel 25 is driven from the crown 20 by the hoisting gear and the round hole wheel, the shaft 24 moves the spring of the main barrel 23 and the spring of the second barrel 31 simultaneously with the movable part. Rewind using 27, 28, 29 and shaft 30.

歯車３４も軸３０により支持されており、この歯車３４が、車３５及びその歯車３６を用いて、車３７及び稼動余力表示文字盤１９を駆動し、稼動余力表示文字盤１９は反時計回りに回転して、針１８に、実際には静止した状態で、稼動余力の増加を表示させる。同時に車３７の突起３８は、車４０の開口部４１の中で自由に移動し、従って車４０は回転しない。   The gear 34 is also supported by the shaft 30, and this gear 34 uses the wheel 35 and the gear 36 to drive the wheel 37 and the remaining working capacity display dial 19, and the remaining working capacity display dial 19 is counterclockwise. Rotates and causes the needle 18 to display an increase in operating reserve while actually stationary. At the same time, the projections 38 of the car 37 are free to move in the opening 41 of the car 40 and therefore the car 40 does not rotate.

巻き上げが２つの香箱にとって少なくとも１０時間の稼動時間に相当する状態に到達すると、針１８は文字盤１９上で１０時間の稼動余力を示す。突起３８も車４０の開口部４１の末端隣接点に到達する。   When the winding reaches a state corresponding to an operating time of at least 10 hours for the two barrels, the hand 18 shows an operating capacity of 10 hours on the dial 19. The protrusion 38 also reaches the end adjacent point of the opening 41 of the vehicle 40.

２． １０時間を超える巻き上げ
巻き上げが継続する場合、車４０は突起３８の作用に基づいて回転を始め、こうして針１８をその文字盤１９と同時に駆動し始めるので、稼動余力表示は１０時間のままである。車４２は歯車４６上に摩擦取り付けされているので、車４２は、自身が歯車４３、車４４、及び歯車４５を介して香箱３１に連結されるような香箱３１の位置に、対応した位置で留まる。 2. Winding over 10 hours If the winding continues, the wheel 40 begins to rotate based on the action of the projection 38 and thus starts to drive the hands 18 simultaneously with its dial 19 so that the remaining working capacity indication remains 10 hours. . Since the wheel 42 is frictionally mounted on the gear 46, the wheel 42 corresponds to the position of the barrel 31 where it is connected to the barrel 31 via the gear 43, the wheel 44 and the gear 45. stay.

車４０はさらに、歯車４６及び角度伝達装置４７を介して、車４８を駆動し、車４８の開口部４９は、車５０の突起５２を受け入れる。巻き上げが約３０時間の稼動期間に相当する状態に到達すると、この突起は開口部４８の末端隣接点に到達する。従って車５０は回転を始め、可動部５３、５５、５６、５７、及び５８により、歯車５９を駆動する。しかし歯車５９は、狼歯歯車可動部６０の存在のため、主香箱２３に対して影響を及ぼさない。 The vehicle 40 further drives the vehicle 48 via the gear 46 and the angle transmission device 47, and the opening 49 of the vehicle 48 receives the protrusion 52 of the vehicle 50. When the winding reaches a state corresponding to an operation period of about 30 hours, the protrusion reaches the end adjacent point of the opening 48. Accordingly, the vehicle 50 starts rotating and drives the gear 59 by the movable parts 53, 55, 56, 57 and 58. But the gear 59, due to the presence of lupus gear movable portion 60, does not affect the main barrel 23.

つまり、滑りストラップを備えたばねの使用により、巻き上げ竜頭２０の作動による巻き上げは、損傷を引き起こすことがなく継続してもよいことがわかる。   That is, it can be seen that the use of the spring with the sliding strap may continue the winding by the operation of the winding crown 20 without causing damage.

３． ストップウォッチ機能を伴わない稼動
腕時計の通常の操作では、主香箱２３のドラムが作動される唯一の要素であり、従って主香箱２３の外歯車２６を介して現在時刻を表示するための歯車列を駆動し、外歯車２６も狼歯歯車可動部６０を駆動し、狼歯歯車可動部６０は、この回転方向において、突起の付いた車５０に対してその動きを伝達する。 3. Operation without a stopwatch function In normal operation of the watch, the drum of the main barrel 23 is the only element that is actuated, so a gear train for displaying the current time via the external gear 26 of the main barrel 23 is provided. driven, external gear 26 also drives the wolf tooth gear movable portion 60, wolf gear movable portion 60 in the rotation direction and transmits the movement against the car 50 equipped with a projection.

計時器が完全に巻き戻されたことを受けて、稼動余力の表示は１０時間のまま、車５０はこれに影響を及ぼすことなくこうして約３０時間回転するが、これはその突起５２が車４８の開口部４９内で自由に回転するからである。稼動の３０時間の終わりに、突起は開口部４９の末端隣接点に到達して、車４８は回転を始める。角度伝達装置４７、歯車４６、及び軸３９、を用いて、稼動余力表示針１８を１０時間の位置から反時計回り方向に回転させ始める。第２香箱３１は作動しておらず、従って車４２は静止しているが、この車は軸３９上に摩擦取り付けされているので、針１８の移動は可能である。   In response to the timepiece being completely rewound, the indication of remaining working capacity remains 10 hours, and the car 50 thus rotates for about 30 hours without affecting it, but this is because the protrusion 52 has a car 48. This is because it freely rotates in the opening 49 of the. At the end of 30 hours of operation, the protrusion reaches the end adjacent point of the opening 49 and the wheel 48 begins to rotate. Using the angle transmission device 47, the gear 46, and the shaft 39, the operating remaining force indicating hand 18 starts to rotate counterclockwise from the position of 10 hours. The second barrel 31 is not actuated, so the wheel 42 is stationary, but the wheel 18 is frictionally mounted on the shaft 39 so that the needle 18 can be moved.

針１８が車４０の開口部４１内における突起３８の移動に対応した経路に沿った移動を完了する、すなわち１０時間経つと、針１８は文字盤１９上で余力ゼロを表示し、従って主香箱２３は約４０時間分解放された状態となる。   When the needle 18 completes the movement along the path corresponding to the movement of the projection 38 in the opening 41 of the wheel 40, i.e. after 10 hours, the needle 18 displays zero remaining power on the dial 19, and thus the main barrel. 23 is released for about 40 hours.

つまり、軸３９を香箱２３に関連づける歯車列に挿入された摩擦車５５の存在のおかげで、針１８がゼロ位置に到達した時点で、香箱２３が完全に解放することを妨げられていないことがわかる。   In other words, thanks to the presence of the friction wheel 55 inserted in the gear train that associates the shaft 39 with the barrel 23, it is not prevented that the barrel 23 is fully released when the needle 18 reaches the zero position. Recognize.

４． ストップウォッチ機能を伴う稼動
ストップウォッチ機能が作動されると直ぐに、第２香箱３１はずっと作動状態に置かれ、稼動余力の表示に影響を及ぼす。第２香箱３１の歯車４５はこれによって、車４４、歯車４３、車４２、及び軸３９を用いて、稼動余力表示針１８の駆動を開始し、針１８は反時計方向に移動を始める。軸３９は歯車４６及び車４０を駆動する。車４０はその歯車４６を介して角度伝達装置４７と噛み合い、角度伝達装置４７は解放車４８を駆動する。 4). Operation with the stopwatch function As soon as the stopwatch function is activated, the second barrel 31 is kept in the activated state, which affects the display of the remaining working capacity. As a result, the gear 45 of the second barrel 31 starts driving the operating remaining force indicating needle 18 using the wheel 44, the gear 43, the wheel 42, and the shaft 39, and the needle 18 starts moving counterclockwise. The shaft 39 drives the gear 46 and the wheel 40. The vehicle 40 meshes with the angle transmission device 47 via the gear 46, and the angle transmission device 47 drives the release wheel 48.

明らかに、主香箱はまだ作動中でありかつ車５０を駆動しており、車５０の突起５２は３０時間後に車４８の開口部４９の末端隣接点に到達し、これに対して、車５０、４８が同時に移動しているので、ストップウォッチ機構が作動した時間が加算される。換言すると、ストップウォッチ機構が３時間使用された場合、突起５２は３３時間後にようやく隣接点に到達する。針１８は１０時間−３時間に等しい稼動余力を表示するので、針１８は主香箱の作動の４０時間後にゼロに到達する。   Obviously, the main barrel is still operating and driving the car 50, and the protrusion 52 of the car 50 reaches the end adjacent point of the opening 49 of the car 48 after 30 hours, whereas the car 50 , 48 are moving simultaneously, the time when the stopwatch mechanism is activated is added. In other words, when the stopwatch mechanism is used for 3 hours, the protrusion 52 finally reaches the adjacent point after 33 hours. The needle 18 displays a working reserve equal to 10 hours-3 hours, so that the needle 18 reaches zero after 40 hours of operation of the main barrel.

主香箱の稼動余力が１０時間未満の時に計測時間の計測を開始する場合、突起５２は車４８も回転させる。これは、このような時に針１８の制御に対して２つの香箱の作用が一緒に加わるのを防ぐために不可欠である。   When the measurement time is started when the operating capacity of the main barrel is less than 10 hours, the protrusion 52 also rotates the wheel 48. This is essential in order to prevent the action of the two barrels together for the control of the needle 18 at such times.

つまり、このようにするためには、車４８はさらに第２香箱３１により駆動される車４２の回転によっても作用されることがわかる。このように、車４８、５０は同じ速度で駆動されることにより、かつ少なくとも１分に等しい歯車振動（香箱３１が１分ずつ進行することから必要とされる）のため、車の突起５２は、車４８の開口部４９の末端に対して相対的に同じ位置に留まる。これらの配置のおかげで、針１８はこうして２つの香箱間で衝突せずに駆動され、主香箱の稼動余力に相当する同一の稼動余力が表示される。   That is, in order to do this, it can be seen that the car 48 is also acted upon by the rotation of the car 42 driven by the second barrel 31. Thus, because the wheels 48 and 50 are driven at the same speed and because of gear vibration equal to at least one minute (required because the barrel 31 advances one minute at a time), the car protrusion 52 is , Stays in the same position relative to the end of the opening 49 of the wheel 48. Thanks to these arrangements, the needle 18 is thus driven without colliding between the two barrels, and the same working capacity corresponding to the working capacity of the main barrel is displayed.

上述の機構は、香箱ばねの手動巻き上げを備えた腕時計の中に組み込まれる。自動巻き上げを備えた腕時計にそのまま応用されてもよいことは明らかである。   The mechanism described above is incorporated into a wristwatch with manual winding of a barrel spring. Obviously, it may be applied as it is to a wristwatch with automatic winding.

このようにして、稼動余力を表示するための機構は、ストップウォッチ機能を作動するのに必要な、１０時間に設定された、稼動時間のみを表示することが提案されており、一方で計時器は、現在時刻表示機能として４０時間の余力を有する。   In this way, it has been proposed that the mechanism for displaying the operating surplus capacity only displays the operating time, which is set to 10 hours, which is necessary for operating the stopwatch function. Has a surplus capacity of 40 hours as a current time display function.

換言すると、表示針１８は：
−ストップウォッチが作動されない限り、計時器の作動３０時間後、
−あるいは、１０時間の余力を要するストップウォッチが作動された直後、
のいずれかに、１０時間からゼロまで逓減的に駆動される。 In other words, the indicator hand 18 is:
-Unless the stopwatch is activated, after 30 hours of operation of the timer,
-Or immediately after a stopwatch requiring 10 hours of surplus is activated,
Any one of these is driven down from 10 hours to zero.
